DETAILED DESCRIPTION

The present invention is a ladder rack and cable cleat system that allows for thermal expansion or contraction of cables that are attached to the ladder rack. FIG. 1 illustrates a ladder rack 50 with ladder rack side rails 52 and ladder rungs 54, 56 that are positioned between the side rails 52 at specified intervals to form the ladder rack 50. As illustrated in FIG. 1, every third rung of the ladder rack 50 is a perforated rung 56 with the sides of the ladder rung having aligned holes 58. As described below, the aligned holes 58 receive the cable cleats 100 that are designed to secure cables 70 to the ladder rack 50.

FIGS. 2-4 illustrate a cable cleat 100 of the present invention securing cables 70 to a perforated ladder rung 56 of the ladder rack 50. As illustrated in FIG. 3, each perforated rung 56 is positioned lower than the non-perforated rungs 54 to enable the cable cleat 100 to be inserted under the cables resting on the ladder rack 50 without lifting the cables 70. As a result, the cable cleats 100 are easy and quick to install.

As illustrated in FIG. 4, the cable cleat 100 is wider than the perforated ladder rung 56. As a result, there are open spaces 80 on both sides of the ladder rung 56. The open spaces 80 provide compensation for thermal expansion by allowing the cable cleat 100 to slide on the ladder rung 56, when necessary.

As illustrated in FIG. 5, the cable cleat 100 includes a cable cleat base 102, a cable cleat cover 120, and three pins 140, 150, 160 with keeper wires 144, 154, 164, respectively. Each pin performs a different function to secure the cable cleat 100. The cable cleat hinge pin 140 pivotally connects the cable cleat cover 120 to the cable cleat base 102. The cable cleat attaching pin 150 secures the cable cleat 100 to the perforated ladder rung 56. The cable cleat locking pin 160 secures the cable cleat cover 120 over cables 70. The keeper wires 144, 154, 164 protect against vibrations and prevent the pins 140, 150, 160, respectively, from sliding out of position. The keeper wires 144, 154, 164 act as a typical cotter pin. The keeper wires anchor the cable cleat pins by being inserted through a hole in the cable cleat pin shaft and then spread to hold the cable cleat pin in position.

The cable cleat base 102 includes a first end 104 designed to slide under the cables 70 resting on the perforated ladder rung 56 and a second end 112. The first end 104 of the cable cleat base 102 includes two downwardly extending base flanges 106. One of the base flanges 106 is positioned on either side of the first end 104 of the cable cleat base 102. Each base flange 106 includes two holes 108, 110 for receiving the cable cleat attaching pin 150 and the cable cleat locking pin 160, respectively. The second end 112 of the cable cleat base 102 also includes two flanges 114 positioned on either side of the second end 112 of the cable cleat base 102. Each flange 114 includes a hole 116 for receiving the cable cleat hinge pin 140.

The cable cleat cover 120 includes a first end 122 with two flanges 124 and a second end 128 with two flanges 130. The flanges 124 at the first end 122 of the cable cleat cover 120 are positioned on each side of the cable cleat cover 120 and each flange 124 includes a hole 126 for receiving the cable cleat hinge pin 140. As illustrated in FIGS. 2 and 5-7, the first end 122 of the cable cleat cover 120 is pivotally connected to the second end 112 of the cable cleat base 102 via the cable cleat hinge pin 140. The cable cleat hinge pin 140 is locked in position by the keeper wire 144 that is inserted in holes 142 in the cable cleat hinge pin 140 to hold the base 102 and cover 120 together. The flanges 130 at the second end 128 of the cable cleat cover 120 are positioned on each side of the cable cleat cover 120 and each flange 130 includes a hole 132 for receiving the cable cleat locking pin 160.

FIGS. 6 and 7 illustrate the installation of the cable cleat 100 on a perforated ladder rung 56 over cables 70. The cable cleat 100 is installed around the cables 70 with the cable cleat cover 120 pivoted upward. After sliding the cable cleat base 102 under the cables 70 resting on the perforated ladder rung 56, the cable cleat attaching pin 150 is inserted through the hole 108 in one of the base flanges 106, through the aligned holes 58 in the perforated rung 56, and through the hole 108 in the second base flange 106. The cable cleat attaching pin 150 is locked in position by the keeper wire 154 that is inserted in holes 152 in the cable cleat attaching pin 150 to hold the cable cleat 100 together. The cable cleat attaching pin 150 prevents lateral movement along the ladder rung 56.

Next, the cable cleat cover 120 is pivoted downward around the cables 70 to confine the cables 70. Once the cable cleat cover 120 is fully closed, the cable cleat locking pin 160 is inserted through the hole 132 in one of the flanges 130 at the second end 128 of the cable cleat cover 120, the holes 110 in the flanges 106 at the first end 104 of the cable cleat base 102, and through the hole 132 in the flange 130 at the opposite side of the second end 128 of the cable cleat cover 120. The cable cleat locking pin 160 is secured in position by the keeper wire 164 that is inserted in holes 162 in the cable cleat locking pin 160 to hold the cable cleat 100 together.

The cable cleat system described with respect to FIGS. 1-7 may be installed without lifting the cables 70 only on every third perforated ladder rung 56 of the ladder rack 50.
